I just ordered the Natalie MacMaster DVD. As far as I know, it's only available from Natalie's website above. Although most of Hayley's performance is on the cutting room floor, I bought it just to see 'Ave Maria'.
The price is Canadian$29.50 with shipping. About US$30 and UK₤15.
My copy of Natalie MacMaster DVD's with guest Hayley, arrived today , it took more or less 8 days (not bad), the envelope has a sticker "International Par avion air - with a PO Box address from Auckland - New Zealand" I thought the shipment was made by DHL from Canada.
